Its not that you have not documented it. The problem is more information overload. With three threads in the microcontroller section of the forum dealing with the 1284 and 644 chips and following them all with interest while I was building the boards I just took the most repeated advice.

In my haste to program and play with the boards I assumed they were all alike. I assumed they all shared the same "Mighty" phrase in the name so I picked up on that to assume they were simular and the bootloaders and files were interchangable.

Now that it has been mentioned in the thread the chances are that fewer people will make the same mistake.

I suffered from the "board type" confusion a little bit with the Bobuino. It pretty much came down to the fact that I was new to the 1284 and didn't realize the difference between boards.

I liked your instructions that came with the Bobuino, they helped me a lot. I don't think you need very much instructions for the Mini because it is so basic. You could make a small right up about the pin out and LED connections. Perhaps include the direct port manipulation code (that included the 1284 bobuino) that Nick Gammon made a will back for all of the Arduino Atmega chips.

By the way, I got my bootloaders into my new boards on the first try! I put a FTDI male header on them, hopefully I will get a sketch loaded this weekend and watch the magic!
